C＃中使用的WebRequest饼干 [英] C# WebRequest using Cookies

问题描述

我有一个WinForms应用程序我一直在运行对消费者帐户的多个测试。的测试，以执行需要一次登录

 字符串PARAMATERS =authmethod = ON＆安培; chkRememberMe = ON＆安培;登录表单型= PWD和放大器;密码=+ pw.Text +＆放大器;用户id =+ uid.Text +＆放大器;用户名=+ uid.Text;
        串strResponse;
        HttpWebRequest的requestLogin =（HttpWebRequest的）WebRequest.Create（https://www.url.com/login.form）;
        requestLogin.Method =POST;
        requestLogin.CookieContainer = cookieJar;
        requestLogin.ContentType =应用/的X WWW的形式urlen codeD;        requestLogin.ContentLength = paramaters.Length;
        粗壮的StreamWriter =新的StreamWriter（requestLogin.GetRequestStream（），System.Text.Encoding.ASCII）;
        stOut.Write（PARAMATERS）;
        stOut.Close（）;        StreamReader的STIN =新的StreamReader（requestLogin.GetResponse（）GetResponseStream（））;
        strResponse = stIn.ReadToEnd（）;
        stIn.Close（）;
 

本脚本适用于登录就好了，问题是，当我需要实际运行，我需要所有的结果返回到一个字符串（HTML结果）测试。

 私人字符串runTestRequest（URI链接，字符串参数）
    {
        字符串testResults =的String.Empty;
        HttpWebRequest的的runTest =（HttpWebRequest的）WebRequest.Create（URL）;
        runTest.CookieContainer = cookieJar;
        runTest.Method =POST;
        runTest.ContentType =应用/的X WWW的形式urlen codeD;
        粗壮的StreamWriter =新的StreamWriter（runTest.GetRequestStream（），System.Text.Encoding.ASCII）;
        stOut.Write（参数）;
        stOut.Close（）;
        StreamReader的STIN =新的StreamReader（runTest.GetResponse（）GetResponseStream（））;
        testResults = stIn.ReadToEnd（）;
        stIn.Close（）;
        返回testResults;
    }
 

但它去，并试图登录。我该如何使用Cookie从本+许多其他的Web请求previous登录请求？

感谢您的帮助。

编辑：

我说这我的code还应该做同样的事情BrokenGlass是除了一点点不同的说法，但仍然无法正常工作。

 的foreach（在responseLogin.Cookies饼干饼干）
        {
            cookieJar.Add（新的Cookie（cookie.Name.Trim（），cookie.Value.Trim（），cookie.Path，cookie.Domain））;
            richTextBox2.Text + = cookie.Name.ToString（）+ Environment.NewLine + cookie.Value.ToString（）+ Environment.NewLine + cookie.Path.ToString（）+ Environment.NewLine + cookie.Domain.ToString（）;
        }
 

解决方案

这样的事情应该工作，我使用类似code保存登录cookie：

  HttpWebRequest的runTest方法;
//...do登录请求
//得到响应cookie的CookieContainer myContainer中=新的CookieContainer（）;
的for（int i = 0; I＆LT; Response.Cookies.Count;我++）
{
   的HttpCookie HTTP_COOKIE = Request.Cookies时[I]
   饼干饼干=新的Cookie（http_cookie.Name，http_cookie.Value，http_cookie.Path）;
   myContainer.Add（新的URI（Request.Url.ToString（）），饼干）;
}//后来：
HttpWebRequest的要求=（HttpWebRequest的）WebRequest.Create（http://www.url.com/foobar）;
request.CookieContainer = myContainer中;
 

I have a winforms application i have been working on that runs multiple tests on consumer accounts. The tests require a one time login in order to execute.

string paramaters = "authmethod=on&chkRememberMe=on&login-form-type=pwd&password=" + pw.Text + "&userid=" + uid.Text + "&username=" + uid.Text;
        string strResponse;
        HttpWebRequest requestLogin = (HttpWebRequest)WebRequest.Create("https://www.url.com/login.form");
        requestLogin.Method = "POST";
        requestLogin.CookieContainer = cookieJar;
        requestLogin.ContentType = "application/x-www-form-urlencoded";

        requestLogin.ContentLength = paramaters.Length;
        StreamWriter stOut = new StreamWriter(requestLogin.GetRequestStream(), System.Text.Encoding.ASCII);
        stOut.Write(paramaters);
        stOut.Close();

        StreamReader stIn = new StreamReader(requestLogin.GetResponse().GetResponseStream());
        strResponse = stIn.ReadToEnd();
        stIn.Close();

This script works for the login just fine, the problem is when i need to actually run the tests i need to return all the results into a string (HTML results).

private string runTestRequest(Uri url, string parameters)
    {
        string testResults = string.Empty;
        HttpWebRequest runTest = (HttpWebRequest)WebRequest.Create(url);
        runTest.CookieContainer = cookieJar;
        runTest.Method = "POST";
        runTest.ContentType = "application/x-www-form-urlencoded";
        StreamWriter stOut = new StreamWriter(runTest.GetRequestStream(), System.Text.Encoding.ASCII);
        stOut.Write(parameters);
        stOut.Close();
        StreamReader stIn = new StreamReader(runTest.GetResponse().GetResponseStream());
        testResults = stIn.ReadToEnd();
        stIn.Close();
        return testResults;
    }

But it goes and tries to login. How can i use the Cookie from the previous login request with this + many other web requests?

Thanks for the help.

EDIT:

I added this to my code yet which should do the same thing as BrokenGlass is saying except just a little different but still doesn't work.

foreach (Cookie cookie in responseLogin.Cookies)
        {
            cookieJar.Add(new Cookie(cookie.Name.Trim(), cookie.Value.Trim(), cookie.Path, cookie.Domain));
            richTextBox2.Text += cookie.Name.ToString() + Environment.NewLine + cookie.Value.ToString() + Environment.NewLine + cookie.Path.ToString() + Environment.NewLine + cookie.Domain.ToString();
        }

解决方案

Something like this should work, I am using similar code to save a login cookie:

HttpWebRequest runTest;
//...do login request
//get cookies from response

CookieContainer myContainer = new CookieContainer();
for (int i = 0; i < Response.Cookies.Count; i++)
{
   HttpCookie http_cookie = Request.Cookies[i];
   Cookie cookie = new Cookie(http_cookie.Name, http_cookie.Value, http_cookie.Path);
   myContainer.Add(new Uri(Request.Url.ToString()), cookie);
}

//later:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.url.com/foobar");
request.CookieContainer = myContainer;
